[Question] Serialize scalar according to type field

[SadE54]

Hi ,

Internally I have a class with a string property and a type property.
the string value is coming from a json file and can contain generic numeric value , with the type (bool , byte , integer , float) set by the type property .
How can I serialize the numeric value of the string according to the type , with a fixed length of 4 byte ?

Thx
